Problem: Certain modded cars have this "door is opening...................................... ok you can get in now" animation and it is super annoying.
My solution: Get rid of that animation, just have the players pop in and out like OG Arma vehicles.
The issue: Everyone and their dog just join massive gangs to try to farm frags at majors or run 4-5 semi trucks of shit. It is not conducive to roleplay, limits other social interactions and makes it hard for any smaller groups to get ahead.
My Solution: Limit gang members to no more than 10 people.
